Computer power cables are essential components that supply electricity to computers and their peripherals. These cables connect the computer's power supply unit to an electrical outlet, ensuring that the system receives the necessary power to operate. They come in various types, including C13, C14, and C15, which differ in shape and function. In addition to standard power cables, there are also specialized cables for specific devices, such as USB power cables for charging and data transfer. Properly managing and maintaining these cables is important for safety and efficiency, as damaged cables can lead to electrical hazards or system failures.
